A signal peptide marketed for firmness and collagen-signalling anti-aging claims; palmitoylated to improve skin penetration.
What does it do?
According to PubMed, a 2026 safety-evaluation framework study testing bioinformatic screening tools on cosmetic peptides found palmitoyl hexapeptide-12 showed sequence homology with extracellular matrix proteins in skin (collagen, elastin, fibronectin) without flagging any toxin or allergen safety concerns, unlike several other tested peptides (DOI: https://doi.org/10.1016/j.crtox.2026.100291). This is a safety-screening study, not a clinical efficacy trial; no dedicated human efficacy RCT for this specific peptide was found in this search.
